LT3512 Datasheet Monolithic High Voltage Isolated Flyback Converter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT3512 Monolithic High Voltage Isolated Flyback Converter.

General Description

The LT3512 is a high voltage monolithic switching regulator specifically designed for the isolated flyback topology.

No third winding or opto-isolator is required for regulation as the part senses output voltage directly from the primary-side flyback waveform.

The device integrates a 420mA, 150V power switch, high voltage circuitry, and control into a high voltage 16-lead MSOP package with four leads removed.
